Question
2. On a cool autumn evening of 70 degrees Fahrenheit, Detective Albert Gebra is investigating a murder/crime scene. Al assumes that the victim had a normal body temperature of 98.6 degrees Fahrenheit when he died (at time m = 0) and Al finds that the body cooled from 85.7 degrees to 81.3 degrees in 11 minutes.
(a) Use this information to find the constants in the function and clearly state your complete model. You may use the nspire to solve any algebraic equation as long as the equation that you are solving is clearly identified.

(b) If at 9:48 PM the body temperature was taken to be 78.4 degrees, use your model to estimate the time of death. Show all steps.
